Question

我有一个工作代码，其中来自MSSQL db的数据用于使用SSIS的脚本组件通过wsdl文件流至SAP Bapiret2私有服务引用。

该代码适用于INT，QA和Stage环境。所有这些环境均具有不同的端点地址和要在IIS上安装的证书。

数据仅约2000行，有10列。样本数据如下：

EngagementName和LocalClientName列被选为BlobColumn。

我得到的错误是：

接收到https://s ***。######。com / **** Gateway的HTTP响应时发生错误。这可能是由于服务端点绑定未使用HTTP协议。这也可能是由于服务器终止了HTTP请求上下文（可能是由于服务关闭了）。有关更多详细信息，请参见服务器日志。
基础连接已关闭：服务器已关闭了预期保持活动状态的连接。
请求通道在00:20:00之后等待答复时超时。增加传递给请求的调用的超时值，或者增加绑定上的SendTimeout值。分配给该操作的时间可能是较长超时的一部分。

我以前在较早的环境中没有收到错误，但是现在对于某些行，我得到了高于错误的消息。整个程序包曾经在20分钟内成功运行，但是现在由于错误，它继续运行，因此我必须手动停止它。

对于解决方案，我将KeepAlive属性设置为false，但这增加了包运行的时间，但仍然出现其他错误。

此外，通过Google搜索，我在BufferWrapper.cs文件中为所有getter setter属性添加了[DataContract]和[DataMember]，但无济于事。但是当我重新打开.cs文件时，它又变回了没有[DataContract]和[DataMember]的早期版本。

还已将超时时间从20分钟更改为10分钟，但没有喘息的机会。

我在脚本组件中的代码如下：
